Sagina subulata (Irish Moss)

If you’re looking for a plant that creates a soft, vibrant green carpet in your terrarium or indoor setup, Sagina subulata, commonly known as Irish Moss, is a fantastic choice. Its tiny leaves and spreading habit make it perfect for ground cover or creating miniature landscapes. Irish Moss features dense, bright green, moss-like foliage that grows in a low mat. It can produce small white star-shaped flowers during the growing season, adding delicate pops of interest to your terrarium floor or garden nook.

Care Requirements for Terrariums

• Light: Prefers bright, indirect light. It tolerates partial shade but grows most compact and vibrant in well-lit conditions.

• Water: Keep the soil consistently moist but not waterlogged. Mist regularly in closed terrariums to maintain humidity.

• Humidity: Thrives in moderate to high humidity, making it well-suited to terrarium environments.

• Temperature: Performs best in temperatures around 15–25°C. Protect from extreme heat or cold drafts.

Pet and Reptile Safety

Sagina subulata is non-toxic to cats, dogs, and most reptiles, making it a safe option for terrariums or households with small animals.

Terrarium Tips

• Ideal as a ground cover to create a lush, carpeted effect.

Irish Moss is a versatile and resilient plant that brings texture, softness, and vibrant green color to terrariums and indoor plant displays. Its pet- and reptile-safe nature, combined with its low-growing habit, makes it perfect for anyone wanting a natural, living carpet effect in small-scale ecosystems.
